Ok yet another question for soft stool..... I am the proud owner of Jackson, black male lab. He has had soft stool since he came home to us. He's 6.5 months old and I've had him since Jan 24th. This is my first dog EVER and he's had what I call soft serve poop since I've had him. 2 stool samples both negative for everything. He's been on boiled chicken and rice, EVO Red, and now Kirkland C&R. I realize the EVO was probably too rich. I'm 25 days into the Kirkland and no improvement. Any recommendations without breaking the bank?
